CHlMES-RELEASING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 360,203, dated March 29, 1887.

Application filed June 15, 1886.

To all whom it may concern.-

Be it known that I, RUFUs B. CARR, of 130s ton, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Chimes-Releasing Mechanism, of which the following is a specification.

My invention relates to contrivances connected with a clock or.clock mechanism for setting in operation other and independent mechanism for a specialor different purposes.

The particular object of the invention organized as here represented is to provide improved means for attachment to a clock mechanism for automaticallyreleasing or setting inoperation the chiming mechanism of what is commonly known as the Westminster or Cambridge chimes, so that chimes ora tune or tunes may be rung upon a series of bells musically tuned to each other at any predetermined time or times during the day of twenty-four hours.

My invention consists in the improvements which I will now proceed to describe, so that 2 5 others skilled in the art may be able to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, the invention being particularly set forth in the claims appended to the 0 description of the construction and operation of the device.

Of the drawings, Figure 1 represents a rear view of the mechanism embodying my invention. Fig. 2 represents a side view thereof,

looking in the direction of 'the arrow in Fig. 1. Fig. 3 represents a sectional view on the line 1 1, Fig. 2, looking in the direction of the arrow in said figure, of a portion of my improvements, designed more especially to show 4 the relationship of the unlocking-levers to the center arbor of the clock. Fig. 4: represents a section on the line 2 2, Fig. 2, looking in a direction opposite to the arrow, showing on an enlarged scale a part of the means for opcrating the unlocking-levers. Fig. 5 represents'a section on the line 3 3, Fig. 1 Fig. 6 represents a side view of the cam-wheels sepa rated.

Similar letters of reference indicate similar 5 parts in all of the figures.

Serial No. 205,284. (No model.)

a represents the frame of the device, or so much thereof, consistent with clearness of illustration, as is necessary to show how the mechanism is supported.

1) represents an arbor of a clock or time mechanism, which in this instance may be supposed to, be a center arbor, and which, as

l is well understood by those skilled in the art,

is regularly revolved, turning once around each hour.

a representsa wheel therein, forconvenience called the center wheel or dial]. rigidly secured to and turning with the center arbor, b.

(1 represents a sleeve or quill turning loose on an arbor, b, and having a disk or flange, e, connected or formed therewith on its front part, and a gear-wheel, f, in like manner connected with its rear part. Center wheel, 0, is provided with a springpressed pin, 9, (shown in Fig. 2, and in dotted lines in Fig. 1,) which passes through and is adapted to snap into one of sixty holes (corresponding with the minute-marks on the dial) formed in the disk e, whereby the latter is locked to and made to revolve with the center Wheel, 0, and arbor 7 5 b. This means is provided for the purpose of disconnecting the chime-releasing mechanism from the clock mechanism to permit the latter to be turned or set without disturbing the parts of the former or to permit the for- So mer to be regulated without molesting the latter.

Gear-wheel f is provided on its inner face with a stud or studs, h, arranged to pass a given point at a predetermed time, for a purpose to be presently explained. The teeth of gear-wheel f intermeslrwith those of another gear-wheel, i, secured to or formed integral with a sleeve or quill, j, turning loosely on a shaft or arbor, is. To the end of the sleevej, o opposite that at which the gear-wheel i is secured thereto, is mounted another gear-wheel,

Z, in such manner that it can be adjusted 011 its sleeve in relation to gear-wheel i, as may be desired. The teeth of gear-wheel Zintermesh 5 with those of another gear-wheel, m, rigidly secured to a sleeve, a, near the inner end thereof, which sleeve is loosely mounted and so as to turn on a stud, o, secured in the frame a. On the extreme inner end of sleeve n is j tached to the frame a above stud 0.

45 heavier than the upper end.

secured a pinion, p, which pinion is made adjustable on sleeve a by means of a check-nut, q. ,,The teeth of pinion p intermesh with those ,ofa gearwheel, '1', mounted on a stud, s, at-

To the hub or side of gear-wheel r, and turning also on stud s, is rigidly secured a pinion, t, the teeth of which intermesh with those of a gearwheel, a, secured to the inner end of a sleeve,

to 1), adapted to turn loosely on sleeve a.

On the outer end of sleeve a is rigidly sccured a cut or cam wheel, 20, and to the outer end of sleeve 12, which extends out to the inner face of wheel to, is in like manner secured a cut or cam wheel, 00, the first-named pattern wheel being arranged just outside of, and p referably constructed little smaller in diameter than the latter wheel, 00.

It will be seen that cam-wheel w and its sleeve a will be directly revolved by gearbe revolved very much faster than wheel :10,

this difference in speed being for the purpose of bringing the two wheels into proper relative position at the desired times.

Mounted loosely 011 a stud or shaft, 1 is a lever, 2, held in substantially vertical position by a pitman, a, connected with the chiming or striking mechanism of common construction, the relationship of said pitman to the chiming mechanism being such that when it is moved in the direction of the arrow, Fig. 1,

the chiming mechanism will be given its initial movement to set it in operation. An angular lever, b, is also mounted near the center of its length on stud 9,, just inside of lever 4 The upper end of the lever b is provided with an outwardlyextending stud, 0, adapted to be brought against the side of lever 2 by the gravity of lever I), below the pivotal point of the same, the lower end of said lever being The upper end of lever Z) is also provided with a laterallyextending finger, d, in the end of which is affixed a stud having journaled thereon an anti-friction roller, 0, extending outwardly parallel with stud c, which anti-friction roller is adapted to bear on the periphery of camwheels to and The lower end of leverb extends down along side of and near to the inner face of gear-wheel f, and has such relation thereto that when said lever is free to swing to such position as that into which its gravity would carry it its lower point-,f, will be brought into position to be struck by pin 7 in the revolution of gear-wheel 61 f, and thus carry the lower point of lever 11 to the left, as viewed in Figs. 1 and 3, moving the upper end of said lever to the right, bringing lug 0 against the side of lever :4, moving the upper end of the latter lever and pitman 65 to also to the right, thus giving the chiming mechanism its initial movement, as hereinbefore described. When, however, anti-friction roller 6 is made to ride on the periphery of wheel in, the upper end of lever Z) will be rocked to the left, Figs. 1 and 3, and the lower point, f, will be held up out of contact with stud 71 on wheel f in the revolutions of the latter.

Cam-wheel 20, which is revolved once around each hour in unison with the center arbor, Z), has cuts or patterunotches formed in its periphery at such points or point as represents the minute or minutes of the hour that it is desired to release the chiming mcchanism,such cuts or pattern notches being of a shape or form that will. permit anti-friction roller 6 to drop therein, and similar cuts or notches are formed in the periphery of wheel a, which is turned once aroundsay once in twenty-four hours-at such point or points as represent the part or parts of the hour in the series or several hours in which it is desired to have the chimes rung.

The several parts described are so timed and adjusted that anti-friction roller 0 will ride on the. periphery of wheels w or x, the notches in such wheels not being brought into conjunction or to register with each other until it is desired to have the chimes rung,whenthe cuts in said wheels will be made to register as they arrive opposite anti-friction roller 6, and said roller will be made to drop into said cuts by the gravity of the lower part of lever I)", bringing the pointf on the lower end of said lever into the path of travel of pin h, which engages with said lever and at the proper moment rocking it upon its pivot or shaft 3 causing lug c in engagement with the side of lever Zto move the upper end thereof and pitman a in the direction of the arrow, releasing and giving to the chiming mechanism its initial movements, in the manner hereinbefore indicated.

A spring may be secured to lever Zr. and to any stationary part of the device in any suitable and convenient manner to insure the prompt and certain action of said lever to cause anti-friction roller 0 to drop into the cuts or notches of the wheels w 00.

One side of the notch in wheel '10 is inclined, as shown by dotted lines in Fig. 3, whereby as said wheel is revolved anti-friction roller 6 is raised from the cut or notch in the wheel to the periphery thereof, at the same time raising the lower point, f, of lever b out of the line of travel of pin 72-, and before the next or same cut or notch in said wheel shall have come opposite the anti -friction roller again wheel as will have passed forward far enough to hold the anti-friction roller on its periphery and the lever b in its operative position, which is the position in which it is represented in Fig. 3.

While the contrivance as here represented is designed to release the chiming mechanism one or more times every day of twenty-four hours, it is obvious that by changing the gearing or relationship of the gearing between gearwheel f and cam-wheels w and a; the latter may be operated faster or slower, so as to release the chiming mechanism as frequently or at as long intervals as may be desired; hence I do not confine myself or expect to be confined to the precise construction and arrangement of parts herein shown, as these may be varied within the limits of mechanical ingenuity or skill without departing from the spirit of the invention.

What I claim,and desire to secure by Letters Patent, is-

l. The combination, with an arbor of atime mechanism, of a wheel mounted on said arbor and provided with a pin or projection, a lever connected with the chimereleasing means,and mechanism, substantially as described, intermediate of the arbor and said lever, whereby a at the proper time said pin or projection is brought into contact with said lever to operate the same and to actuate the chimes-releasing means, as set forth.

2. The combination, with the arbor and its wheel secured thereto, of the disk 0, its sleeve and gear-wheel f, loosely mounted on said arbor, spring-pressed pin g, for connecting said wheel to said disk, and mechanism connected with said gear-wheel], as set forth..

.3. The combination, with the arbor and its wheel, of a time or clock mechanism, the

mechanism for controlling the chimes-releasing devices, and mechanism, substantially as described, for detaching the arbor and wheel from the mechanism for controlling the chimesreleasing devices, as set forth.

4. The combination, with the arbor and its wheel of atime mechanism,of the wheelfiprovided with a pin] or projection, h, the camwheels 10 and w, and mechanism, substantially as described, intermediate of said wheel 7 and cam-wheels, whereby the latter are revolved at varying speeds, lever b, lever z, and devices connecting said lever with the chimes mechanism, as set forth.

5. The combination, with arbor 1), wheel 0, gear wheel f, connected with said wheel 0 and provided with the pin or projection h, of 5 cam-wheels w x, lever I), provided with the lug c, and anti-friction roller 6, lever z, and devices connecting said lever with the chimes mechanism, as set forth.

In testimony whereof I have signed my name 50 to this specification,in the presence of two subscribing witnesses, this 8th day of June, 1886.
